Dynamic modeling and analysis for two-stage helical gear systems

Abstract

Abstract With the increasingly stringent restrictions on vibration and noise generated by the gear system, it has drawn widespread attention to the ways of predicting and controlling. In order to obtain accurate dynamic characteristics and reflect real bearing collisions, a nonlinear bearing model were proposed in this study, according to which a 9-freedom model of the dynamic transmission system with the two-stage helical gears was established. The impact of bearing clearance on the gear system could be revealed by analysing the dynamic response. This article contributes to the study of vibration modelling and monitoring of a transmission system with two-stage helical gears.
